Quotient rule – Complete video tutorial
Why use the quotient rule?
The simple answer to this question is there is no choice. In other words it is not possible to derive every function using basic differentiation. Take a look at the function below. It is not a simple function. Due to the fact, there is a quotient. It appears as if there are two separate functions being divided with each other. The high function is being divided with the low function. Therefore, the example below requires the quotient rule to take the derivative.
Let’s say we want to find the derivative of the function given above. Not using the quotient rule, requires manipulating this function so it does not have a quotient anymore. As a result, deriving this function would be infinitely more complicated. Fortunately, this is not necessary and deriving this function can be done quickly and easily.
When to use the quotient rule?
Anytime there are two things are being divided with each other is the general rule of thumb. Look at the same example listed above. Notice how the high is being divided by the low. Hence, this is a clear indication to use the quotient rule in order to differentiate this function.
